I have reviewed the Soils and Vegetation information Bowie Resources Limited (BRL) provided
for the Waste Refuse Disposal Area (WRDA). Overall, BRL did a good job of the baseline data
collection. I do have a couple comments as discussed below.
Soils Information -Rule 2.04.9 and 4.06
BRL provided adequate soils baseline survey as required by Rule 2.04.9.
2. Page 2.05-38 has been revised to include the topsoil to be removed from the WRDA.
BRL does not say or reference a map showing where the topsoil from the initial
development will be stockpiled. Please include the identification of the topsoil stockpile
where the initial topsoil will be stored, and a map showing the location.
For past revisions, BRL has committed to reporting the volume of topsoil actually
salvaged and placed in the stockpile. Please include this commitment for the salvaged
topsoil from the initial lift.
Subsequent to the first lift BRL proposed to salvage topsoil in advance of each 50-foot
lift and direct hauling it to the completed bench. This is a good reclamation technique.
Please provide a commitment to report the depth and volume of topsoil that has been
salvaged in advance of disturbance and replaced on each lift.
Vegetation and Revegetation -Rule 2.04.10 and 4.15.7
BRL identified two vegetation communities associated with the WRDA proposed
disturbance - a mixed shrubland and a juniper woodland. Both community types were
quantitatively sampled for cover and production. BRL has pre-established reference
areas for both of these vegetation types that were also sampled in July 2003. Rule
4.15.7(3) requires the permittee to demonstrate statistically that each proposed reference
area is comparable to its equivalent area to be disturbed in terms of vegetative cover and
herbaceous productivity. BRL has not provided a statistical compazison.
